 - [types.ts](./src/types.ts): Types of JSON-RPC messages used to communicate between Apps & their host
   - Note that MCP Apps also use some standard MCP messages (e.g. `tools/call` for the App to trigger actions on its originating Server - these calls are proxied through the Host), but these types are the additional messages defined by the extension
 - [examples/simple-example](./examples/simple-example): Example Server + Apps
-  - [server.ts](./examples/simple-server/server.ts): MCP server with two tools that declare UI resources of Apps to be show in the chat when called
+  - [server.ts](./examples/simple-server/server.ts): MCP server with three tools that declare UI resources of Apps to be show in the chat when called
   - [ui-react.tsx](./examples/simple-server/src/ui-react.tsx): React App returned by the `create-ui-react` tool shows how to use the `useApp` hook to register MCP callbacks

+  - [ui-raw.tsx](./examples/simple-server/src/ui-raw.ts): same as vanilla App but doesn't use the SDK runtime (just its types)
 
 - [message-transport](./src/message-transport.ts): `PostMessageTransport` class that uses `postMessage` to exchange JSON-RPC messages between windows / iframes
